Why does LinkedIn have this character limit?

LinkedIn raised its post limit from 1,300 to 3,000 characters in 2020 as the platform shifted toward long-form, opinion-driven content. The 'see more' fold sits at 140 characters on desktop and 210 on mobile — the practical limit for whatever you write before someone has to click to expand. Studies from Hootsuite and Buffer show that LinkedIn posts of 1,500–2,500 characters perform best for engagement.

Tips for Writing Better LinkedIn Content

1Open with the conclusion

The first 140 characters are all most readers see. Lead with your sharpest insight or the surprising finding — then unpack it below the fold.

2Use line breaks aggressively

LinkedIn rewards short paragraphs. A wall of text gets scrolled past. Break every 1–2 sentences for scannability.

3Hashtags: 3–5 is the sweet spot

LinkedIn's algorithm caps hashtag impact at around 5 per post. Pick narrow, professional tags rather than broad ones like #business.

4Headlines beat job titles

Your 220-character headline appears under your name everywhere on LinkedIn. Replace 'CEO at Company' with a value statement: 'Helping fintechs ship 10× faster | CEO at Acme.'

5About sections: tell a story

Use the 2,000-character About to share an arc, not a resume. The most-clicked About sections start with a vivid moment, not 'I'm a seasoned professional.'
